Reaction Steps

15 g (67.2 mmol) of 5-chloro-2-(methylsulfanyl)pyrimidine-4-carbonyl chloride are dissolved in 35 ml of dioxane and cooled to 5° C. 57.3 g (0.4 mol) of 7N ammonia in methanol (about 12% strength solution) are slowly added dropwise to the cooled solution. During the addition, the reaction temperature was kept below 15° C. After the dropwise addition had ended, the reaction mixture was allowed to warm to room temperature and stirred for about 15 hours. The mixture was then added to water and the precipitated 5-chloro-2-(methylsulfanyl)pyrimidine-4-carboxamide was isolated (7.7 g, yield 53% at a purity of 95%).
